Objective: Autologous osteochondral cartilage repair is a valuable reconstruction option for cartilage defects, but the accuracy to harvest and deliver osteochondral grafts remains problematic. We investigated whether image-guided methods (optically guided and template guided) can improve the outcome of these procedures. Design: Fifteen sheep were operated to create traumatic chondral injuries ...

abstract:   introduction: due to the importance of influenza type a (h1n1) as an epidemic disease as well as the type of educational method applied, this study investigated the effects of educational workshop method on students' influenza type a (h1n1)-related knowledge.   methods: in this quasi-experimental study 67 undergraduate students in school of health, isfahan university of medical scie...

Background: To assess the effectiveness of repeated transvaginal ultrasound-guided ovarian interstitial laser treatment in the management of anovulatory patients with polycystic ovary syndrome (PCOS). Materials and Methods: A retrospective study was performed in our department on 27 anovulatory PCOS women who failed to respond to the first ultrasound-guided transvaginal ovarian interstitial las...

Detecting damages in its early stage, and hence, to ensure the safety and reliability of structures is of vital important. Guided waves have been recognised as one of the promising damage detection techniques that are sensitive to small and different types of damages. The understanding of guided wave propagation and scattering phenomena at the damages is one of the fundamental elements to facil...

This paper presents the phased array beamforming and imaging using guided waves in anisotropic composite laminates. A generic phased array beamforming formula is presented, based on the classic delay-and-sum principle. The generic formula considers direction-dependent guided wave properties induced by the anisotropic material properties of composites. Moreover, the array beamforming and imaging...

Background: Observance of professional ethics by teachers and educators plays a very important role in creating a favorable ethical climate in the educational environment. Teachers' professional ethics have been discussed from numerous philosophical perspectives. In the meantime, one of the philosophers of existentialism who is particularly concerned with the issue of ethics in the human world ...

INTRODUCTION Previous studies have shown that the administration of supplementary oxygen (O2) in hospitalised patients outside the intensive care units (ICU) was usually empirical, inappropriate and not in compliance with physiological guidelines. It has been suggested that routine use of portable pulse oximeters in general wards plus in-service education of doctors and nurses may ameliorate th...
